x-serve fails

[mike]

Hi,

I am new to Linux, but have used Unix for several years -- however, only 
as a user, never as an administrator.

I installed Ubuntu seemingly successfully. However, when trying to 
login, gdm tries to start up and fails, resulting in an error message 
that the GUI has been disabled.

At no point during the setup procedure was I asked anything about 
display -- card, resolution, etc. Further, I have an ATI All-In-Wonder 
card installed in the AGP slot, while the motherboard has its own 
video-output onboard.

Needless to say, the display works, which makes the error message all 
the more strange. Any help would be appreciated as I would really like 
to get this to work.

Thanks.

Mike
